Given numbers are 309, 422, 217, 658

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(309, 422) = 130398

GCD(309, 422) = ( 309 x 422 ) / 130398

= 309 / 422

= 309

Step2:

LCM(1, 217) = 217

GCD(1, 217) = ( 1 x 217 ) / 217

= 1 / 217

= 1

Step3:

LCM(1, 658) = 658

GCD(1, 658) = ( 1 x 658 ) / 658

= 1 / 658

= 1

So, Greatest Common Divisor of 309, 422, 217, 658 is 1
